Abstract

The lynx Lynx canadensis is a common predator in the boreal forests of North America Its population fluctuates during a 9 to 11year cycle in synchrony with the population size of its main prey the snowshoe hare Lepus americanus Using adult museum specimens we studied changes in skull and hence body size of the lynx in Alaska during the second half of the 20th century The population cycle in Alaska averaged 9 years similar to that reported in the neighbouring Yukon Using harvest data of lynx as an estimate of population size we found that skull size was negatively related to population size This relationship was strongest not for the population density in the year of death X but for year X3 a carryover effect from the first year or years of life indicating that conditions during the fastgrowth years are determining body size We suggest that the densitydependent effect is probably due to changes in food supply either resulting from the adverse effects of competition or a possible diminished availability of food Two skull parameters decreased significantly during the second half of the 20th century We do not know the cause for the year effect and suggest that it might be due to a longterm change in the availability of prey Canine size did not change during the study period probably an indication that snowshoe hares maintained their status as the main prey of the lynx throughout the study periodWe are grateful to Link Olson Gordon Jarrell Brandy Jacobsen Jonathan Fiely and Charlene Fortner for their help and encouragement before and during our work at the University of Alaska Museum of the North at Fairbanks to Howard Golden Alaska Fish and Game Department for harvest data to Merav BenDavid for her advice in obtaining data and Eli Geffen Charley Krebs and John Wright for comments and Naomi Paz for editing the manuscript This work was partially supported by the Israel Cohen Chair for Environmental Zoology to YYT
